I spoke a bit too soon (I haven't played around with GNUStep for a while).
The crashes only occurs in the Content Inspector Panel of GWorkspace.app.
Although the slowness of displaying images is in all apps. I tried Adam
suggestion in setting NSGlobalDomain GraphicCompositing to NO, but it
didn't help much.

FWIW, have is the error I got with GWorkspace.app:
